12. Signal generation timing

1) In I/O Interface mode

SCLK0 output mode

Immediately after rise of last SCLK0 signal

(See Figure 3.9.17.)

Timing for send

interrupt

generation

SCLK0 input mode

Immediately after rise (Rising mode) or fall (Falling mode) of

last SCLK0 signal

(See Figure 3.9.18.)

SCLK0 output mode

Immediately after final SCLK0 (When received data are

transferred to receive buffer 2 (SC0BUF))(See Figure 3.9.19.)

Timing for

receive interrupt

generation

SCLK0 input mode

Immediately after final SCLK0 (When received data are

transferred to receive buffer 2 (SC0BUF))(See Figure 3.9.20.)

Note:

In 9-Bit and 8-Bit

+ Parity mode, interrupts coincide with the ninth bit pulse. Thus,

when servicing the interrupt, it is necessary to wait for a 1-bit period (to allow the

stop bit to be transferred) to allow checking for a framing error.
